Abstract

Fehlersicheres Automatisierungssystem mit Standard-CPU und Verfahren für ein fehlersicheres AutomatisierungssystemFail-safe automation system with standard CPU and Method for a fail-safe automation system

Die Erfindung betrifft ein fehlersicheres Automatisierungssystem mit Standard-CPU und ein Verfahren für ein fehlersicheres Automatisierungssystem. Das fehlersichere Automatisierungssystem besteht aus:

  • einer oder mehreren Standard-CPU-Baugruppen (CPU) zur Verarbeitung von Sicherheitsfunktionen
  • einer oder mehreren fehlersicheren Peripheriebaugruppen (F-SM, speziell bei Ausgaben: F-DO-SM) zur fehlersicheren Eingabe vom Prozeß und fehlersicheren Ausgabe an den Prozeß
  • einem oder mehreren Kommunikationskanälen (Kommunikationsmedien und ggf. Kommunikationsbaugruppen) zur Kommunikation zwischen CPUs und F-SMs sowie zwischen CPUs.

The invention relates to a fail-safe automation system with standard CPU and a method for a fail-safe automation system. The fail-safe automation system consists of:
  • one or more standard CPU modules (CPU) for processing safety functions
  • One or more fail-safe I / O modules (F-SM, especially for outputs: F-DO-SM) for fail-safe input from the process and fail-safe output to the process
  • one or more communication channels (communication media and possibly communication modules) for communication between CPUs and F-SMs and between CPUs.
